Description & Features

Designed for hydraulic fluid transfer across demanding mobile applications, the Danfoss / Eaton Fluid Coupling 1/4 FP is a female half quick disconnect coupling from the Hansen 5100 Series.

No special tools are required for connection or disconnection, and the design exceeds ISO 16028 operating pressure standards. The Aeroquip sub-brand designation reflects Eaton's Hansen product line heritage.

Hey, will this here fitting work for hooking up to a hydraulic wet line on a dump truck?
Answer by: Customer Support on Apr 8, 2026, 9:29 AM
It's designed for use on on-highway hydraulic wet lines, so it should work well for your dump truck application. It's also good for refuse vehicles and bulk liquid transfer systems.
